Certainly not: Igneous rocks vary in mineralogy from Felsic to Mafic, which encompassed all sorts of compositions. Does a Granite appear the same as a Basalt? No, because they have different mineralogies, and different minerals have different colours and textures. This is visible in every rock.

∙ 14y agono, for example
Granite is made of potassium feldspar, quartz, playgirls feldspar, bootie's, and amphibian
Periodicity is composed of Pyroxene, Olivine, and Amphibian and maybe a very very very very small bit of Plexiglas feldspar
so no they are not made of all the same minerals
they are all different and they are not made of all the same minerals

How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
Two rocks that have the same general chemical and mineral composition?
According to the New York State Earth Science Reference Tables, the two rocks that have the same general chemical and mineral compositions are igneous rocks called andesite and diorite. They both have a composition that consists of quartz, plagioclase feldspar, biotite, pyroxene, and amphibole.
Why do the three rock groups contain the same basic composition?
All rocks are some arrangement of Earth's magma. Igneous rocks are hardened magma. Sedimentary rock are from weathered material from igneous, sedimentary, or metamorphic rocks. Metamorphic rocks have the same composition but are subject to extreme heat and pressure and hence change their crystal structure.
Is it possible for two igneous rocks to have the same mineral constituents but different names?
Yes, depending on the conditions under which it solidified.
What do the three major groups of rocks have in common?
The three major groups of rocks have several things in common. The mineral composition is the same and this is why they will all turn into each other at some point.
Why do igneous rocks that have the same composition sometimes have different sizes of mineral grains?
This is as a result of difference in the rate of cooling of the Igneous rocks.

Can two igneous rocks be made of the same minerals but have different names?
Yes. The grain texture also matters. For example, basalt and gabbro have the same mineral composition, but basalt, which forms on the surface, has microscopic grains while gabbro, which forms underground, has larger mineral grains.
How are the three types of rocks similar?
It all depends on the rock type in question. But basically, to an extent in terms of Igneous Composition, most Igneous rocks are composed of the Minerals; Quartz, Feldsper and Mica Mineral (either of/both the Muscovite and Biotite).
Is it possible for two igneous rocks to have the same mineral constituents but different names?
Yes, depending on the conditions under which it solidified.
Are diorite and andesite similar?
Yes. Diorite and andesite are igneous rocks with the same composition. Andesite is the extrusive equivalent of diorite, which is intruisive.
What is the composition of ocean crust?
It is mostly composed of basalt, and few other mineral types. It is made mostly of igneous rock, same with continental crust.
How are igneous and sedimentary rocks the same?
their both rocks
Are the diamonds formed the same way as igneous rocks?
No. Igneous rock is formed from the solidification of magma or lava. Diamond is a mineral which is formed at great depth below the surface, from intense pressure and heat.
Are sedimentary and igneous rocks the same?
no
